This topic was in a post last October and didn't look like it got resolved.

I am having the same issue. RealDrums are the only Real track in the style.

I have a brand new Dell Vostro 430 with a super fast processor and Windows 7. i7 core processor is super quick.
Sound card is an SB X-Fi titanium that I purchased after receiving the machine. The original SB X-Fi card I ordered with the Dell COULD NOT do "what you hear" or "stereo mix" recording as it is sometimes known. New card resolved that.

BB 2011 when rendering audio to WAV has the Realdrums falling behind after about 3 bars. MIDI is being processed by Dxi direct render. I have turned OFF the drum count in - no difference.

Song sounds great in BB2011 during playback - perfect timing.

I am able to render in REAL TIME to an audio editor - but that's only OK for a short 3 minute song - and is not my #1 choice.

Latency is auto set to 192.

Anything else I can try - or might be missing?

Thanks,
